Abstract
Congenital spherocytosis is an entity that is often misdiagnosed in the neonatal period. Only one third of patients with this disease are diagnosed in the first year of life. This disease is a relatively common entity to be considered in the differential diagnosis of all neonates with early jaundice and hemolytic disease. There is the misconception that the diagnosis of spherocytosis cannot do it after the neonatal stage but data from a mean corpuscular hemoglobin concentration, red cell distribution width and osmotic fragility test linked to the history we can help make an accurate diagnosis.
